which it appertains to make and use the same.

My invention relates to a novel construction in a windmill, the object being to pro- .vide a device of this character in which the wind-wheels are held facing the wind at all times and drive a common shaft and when bolted together will be out of operation; and it consists, further, in the specific means for controlling said wheels and the gearing between the same and a shaft actuated thereby; and it consists in the features of construction and combinations of parts, hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a view in front elevation of a windmill-tower and motor mounted therein constructed in accordance with my invention. Fig. 2 is a horizontal section of same on the line 22 of Fig. 1. Fig. 3 is a fragmentary detail section on the line 3 3 of'Fig. 2 and shows the vane in side elevation. Fig. 4 is a fragmentary detail vertical section on the line 4 4 of Fig. 2. Fig. 5 is a fragmentary detail plan view, on an enlarged scale, showing the means for regulating the tension of springs for holding the wind-wheels normally facing the wind. Fig. 6 is a fragmentary detail vertical section on the line 6 6 of Fig. 4.

My said device comprises the tower or hood at the top of the tower A of a windmill, through which a vertical shaft B passes, which is adapted to be driven from the windwheels C, geared thereto, as hereinafter described. Loosely journaled on said shaft B is a turn-table D, in which a pair of vertical shafts E are journaled at their lower ends, said shafts being journaled between their ends and at their upper ends in plates F and G, loosely mounted on said shaft B. Loosely mounted on said shafts E are the free ends of the arms of supporting frames or brackets H, each of which carries a j ournal-box J, in which the shafts of said wind-wheels C are 'journaled, said shafts carrying bevel-pinions ends of horizontal shafts K, which at their other ends carry bevel-pinions K meshing with bevel-pinions L on said shafts E. The latter carry spur-pinions M, meshing with the spur-gear N on said shaft B, which is thus revolved, said gearing being so arranged that both said wind-wheels revolve in the same direction and serve to revolve said shaft B always in the same direction. Mounted on said plate F and surrounding said shafts E are two toothed plates 0, each engaging one end of a spiral spring P, the other end of which engages one of the arms of each of said frames II and serves to hold the same in engagement with a stop Qin the turn-table D', and in this position the planes of the wind-wheels C are disposed substantially at right angles to the plane of the vane R, by means of which said turn-table is revolved in an obvious manner. The said springs serve to hold said wind-wheels yieldingly facing the wind and serve, further, as governors to enable the said wind-wheels to turn out of operative position in the event that the wind should increase in velocity beyond a safe point. By means of said toothed wheels O the tension of said spring is regulated in an obvious manner, the same being held in position relatively to the plate F by means of pins S. In the event that it should be desired to turn said wheels C out of operative position I provide simple means for accomplishing this purpose. These means consist in providing a central opening through the upper end portion of the shaft B for the passage of a cable T, which is connected at one end with a crosshead U, the ends of which project through longitudinal slots on said shaft B and at their free ends engage a vertical movable collar V on said shaft, said cable being turned over a plurality of pulleys W and depending at its free end near the ground. Connected with the said collar V at one end are two cables X, which pass downwardly and are turned over idlers Y on opposite sides of said vane R, thence pass through an opening Z in said vane in opposite directions, there being idlers 27 disposed in said opening, and are connected at their other ends with said frames H adj acent thejournals of said wind-wheels. Obviously by pulling on said cable the said collar V will be raised and said cables X will act to turn said wind-wheels toward said vane against the action of said spring P, and they will thus be held out of operative position. The connection between said cable T and said cross-head is so made as to permit of free relative rotation of both members, thus abviating the possibility of said cable T being twisted by the revolution of said shaft V.

In order to obtain the best results, it is essential that the wind-wheels C should be disposed as nearly as possible in alinernent with the drive-shaft B, as if the same project normally very far forward of said shaft they will tend to overcome to some extent the action of the vane R.

I desire to call particular attention to the yielding means for holding the wind-wheels normally in operative position, as this forms one of the most essential features of my invention and prevents breakage of the operative parts by wind of high velocity.

I claim as my invention 1. In a Wind-motor, the combination with the drive-shaft, of an independently-rotatable turn-table, two vertically-disposed shafts carried thereby, frames pivotally mounted on said last-named shafts and carrying windwheels, gearing between said wind-wheels and said drive-shaft, and springs engaging said frames for holding said wind-wheels yieldingly in operative position.

2. In a wind-motor, the combination with the drive-shaft, of an independently-rotatable turn-table, two vertically-disposed shafts carried thereby, frames pivotally mounted on said last-named shafts and carrying windwheels, gearing between said wind-wheels and said drive-shaft, springs en aging said frame for holding said windhee s in operative position, and means for adjusting the tension of said springs.

3. In a wind-motor, thecombination with the drive-shaft, of an independently-rotatable turntable, a vane carried thereby, two vertically-disposed shafts on said turn-table, a frame pivotally mounted on each of said last-named shafts, a wind-wheel revolubly mounted in the free end of each of said frames and disposed on relatively opposite sides of said vane, stops on said turn-table to limit the movements of said frames in one direction, springs for yieldingly holding said frames in engagement with said stops to maintain said wind-wheels normally in operative position, and earing between said wind-wheels and said drive-shaft.

4. In a wind-motor, the combination with the drive-shaft, of an independently-rotatable turn-table, a vane carried thereby, two vertically-disposed shafts on said turn-table, a frame pivotally mounted on each of said last-named shafts, a wind-wheel revolubly mounted in the free end of each of said frames and disposed on relatively opposite sides of said vane, stops on said turn-table to limit the movements of said frames in one direction, springs for yieldingly holding said frames in engagement with said stops to maintain said wind-wheels normally in operative position, gearing between said windwheels and said drive-shaft, and means for throwing said wind-wheels out of operative position against the action of said springs.

5. In a wind-motor, the combination with the drive-shaft, of an independently-rotatable turn-table, a vane carried thereby, two vertically-disposed shafts on said turn-table, a frame pivotally mounted on each of said last-named shafts, a wind-wheel revolubly mounted in the free end of each of said frames and disposed 'on relatively opposite sides of said vane, stops on said turn-table to limit the movements of said frames in one direction, springs for yieldingly holding said frames in engagement with said stops to maintain said wind-wheels normally in operative position, earing between said windwheels and said drive-shaft, means for throwing said wind-wheels out of operative position against the action of said springs, said means including cables secured at one end to the free end portions of said frames and pass-' ing in opposite directions through an opening in the vane and connected at their other ends with a collar lon itudinally and revolubly movable on said drive-shaft, idlers over which said cables are trained, and means for imparting longitudinal movement to said collar.
